About Maruto Seika
Maruto Seika Co., Ltd. (マルト製菓株式会社) is a confectionery maker founded in 1946 in Fukuyama City, Hiroshima Prefecture. Its Nagasaki castella (長崎かすていら) is the company's signature long-seller.
What is castella
Castella (カステラ) is a Japanese sponge cake introduced to Nagasaki by Portuguese traders in the 16th century. Made from egg, sugar, wheat flour and a touch of starch syrup and honey, it is prized for a dense-yet-moist, fine-textured crumb — distinct from a Western airy sponge.
Made with care
Maruto Seika makes this castella with plenty of fresh eggs delivered daily from carefully selected producers, finished into a fine, smooth batter. It is lovely as it is, and the maker also suggests enjoying it chilled or lightly toasted.
